<p>Type 2 Diabetes mellitus (T2DM) is a widely spread metabolic clinical condition that enhances the risk of developing diabetic cardiomyopathy and atherosclerotic cardiovascular disease (CVD). The close connection between T2DM and CVD leads to the establishment of the common soil theory, which assumes that both conditions share genetic and environmental factors determining this connection. Most of the affected patients have common risk factors for both T2DM and CVD, such as inflammation, thrombophilia, insulin resistance, dyslipidemia, obesity, and insulin resistance. Various studies have updated and investigated the environmental, genetic, and epigenetic causes of CVD and T2DM. Despite much research, there is still much scope to study the specific pathophysiological association between T2DM and CVD. Therefore, to explore these associations, it is important to provide a thorough explanation of the genetic, epigenetic, and environmental factors included in the simultaneous development of both disorders. This review study in-depth discusses the latest known facts about the genetic and epigenetic similarities between T2DM and CVD. MicroRNAs (miRNAs) and long non-coding RNAs (lncRNAs) are among these characteristics; their disrupted regulation has been implicated as an etiological factor and has been linked to the advent of both disease states. Investigating the link among these conditions could provide fresh hope for future research regarding an integrated pathophysiological approach and future panoramas for the field.</p>
